I just downloaded JuliaPro 1.5.3 and am trying to follow this tutorial exactly: [Julia Tutorial on YT](https://www.youtube.com/watch?v=ei-xnVid3QY&ab_channel=TheJuliaProgrammingLanguage). I went into Atom and tried to update the packages as was shown in the tutorial by issuing the following command:

```julia
(@JuliaPro_v1.5.3-1) pkg> up

```

But this gave me the following error:

```julia
ERROR: expected package `Juno [e5e0dc1b]` to be registered

```

I don’t understand what this means…How do I get Juno “registered” so that I can resolve this and continue on with the tutorial?

I would try `]registry up` and if that fails remove the registry entirely (it will get reinstalled the next time it is needed).

Thanks! I removed the registry and after it reinstalled it worked!

I’d like to add some information to @hendri54’s answer and hopefully help other beginners like me.

1. Registries are folders under `~/.julia/registries/`. In my case, there are two registries: “[General](https://pkgdocs.julialang.org/v1/registries/)” and “JuliaComputingRegistry”. To “remove the registry” means to delete defected folders under `~/.julia/registries/`. For example in this case, delete `~/.julia/registries/General` which `Juno` is registered to.
2. After deleting, you can [manually add](https://pkgdocs.julialang.org/v1/registries/#Adding-registries) `General` back using

```julia
(@JuliaPro_v1.5.4-1) pkg> registry add https://github.com/JuliaRegistries/General

```

Looking back, I probably had messed `General` up by interupting the update process. `General` should have subfolders named from `A` to `Z` but in my case there were only `A` to `G`. `Juno` should be in the subfolder `J`, hence the error message. Moreover, `~/julia/registries/General/Registry.toml` was missing, so Pkg didn’t even know this registry exists, let alone to reinstall it automatically.
